Woodsman 3 #1 Posted November 22, 2010 Hello, Can anyone tell me the correct diameter of the main drive pulley on the single stage snowblower? This is a 36" blower on a C-160. Someone has replaced the original and I'm fairly certain it's too big. The belt rubs on the housing, the belt is too tight, and it rubs on the front axle of the tractor. I'm replacing the chain and sprockets and would like to replace this pulley with the correct size as well. Current pulley is 5.5" Shaft dia. is 3/4" Thanks for any help!

Forest Road 594 #2 Posted November 22, 2010 Your pulley seems right. I've owned 3 of these units and the pulley is so close to the blower that the belt does rub a bit. And the belt needs to be really tight to keep the white SH#@ moving. There was a guy on here some time ago who went an inch smaller on the pulley. He claimed increased throwing distance at a much higher RPM. Hope this helped. Share this post Link to post Share on other sites
Kelly 1,029 #3 Posted November 22, 2010 If you have the idler pulley in the wrong spot the belt will rub on the axle, I don't have pictures but I just put my blower on tonight, and my son tried putting the belt over the pulleys incorrectly it will work but not right Share this post Link to post Share on other sites
wallfish 16,780 #4 Posted November 22, 2010 :thumbs: Here's a look at one. I'm not sure you could add a larger pulley since it's already so tight to the blower. I can measure mine in the day light tomorrow. http://www.wheelhorseforum.com/index.php?showtopic=5522 Share this post Link to post Share on other sites

Woodsman 3 #7 Posted November 22, 2010 You folks are amazing. Thanks for the replies. I'll take a look at how I had the belt routed. I just picked up a pair of C-160's and will probably be here a lot in the future. Thanks again for the help! Share this post Link to post Share on other sites
